The Freestyle check box in the Render tab reads "Freestyle SVG Export" instead of "Freestyle"
I can confirm that the correct tab is &quot;Freestyle SVG Exporter&quot; as introduced officially into Blender in this commit in 2014 which had more unwieldy title of &quot;Export Freestyle edges to an .svg format&quot; with it shortly thereafter being changed to &quot;Freestyle SVG Exporter&quot;, which is where it currently resides.
Poking around tutorials for Freestyle, a lot of them date from about 2013, which makes me think that the initial plugin source (which I'm having a difficult time locating at the moment) may have simply gone with &quot;Freestyle&quot;.
